讨论一类非线性脉冲中立型时滞抛物方程组解的振动性,利用一阶脉冲中立型微分不等式给出了该类方程组在Robin,Dirichlet边界条件下所有解振动的若干充分条件.所得结果充分反映了脉冲和时滞在振动中的影响作用.
This paper discusses the oscillation of the systems of a class of nonlinear impul: sive neutral delay parabolic equations. Some sufficient conditions for the oscillation of all solutions are given under Robin and Dirichlet boundary conditions by using impulsive neutral differential inequalities of first order. The results fully reflect the influence action of impulsive and delay in oscillation.
